N Drawing.

To all whom it may concern:

Be it known'that I, PAUL REIMANN, a

subject of, the -King of Saxony, residing at Trehwitz, near Greiz, Vogtland, Germany, have invented certain new and useful Improvements in Processes for Preparing Paste Used as NVeavers" Glue or for other Similar Dressing Purposes, of which the I following is a specification.

The present invention deals with a process for producing a paste used as weavers glue or for other similar dressing purposes. The weaversglue, made in accordancewith the new method, is easily and readily ab-,

sorbed by the yarn; it also penetrates with great facility into the interior of'the'thread to be dressed, rendering it smooth and round and imparting thereto a great tensile strength. Inaddition such. a dressing substance cannot be easily rubbed away from the thread during the weaving process, and consequently it does not raise dust. The dressing material made according tothe new process does not require any further 'addition of the chemical compounds otherwise used which frequently have an adverse infiuence on the durability of the thread and solutions or pastes of potato-starch or potato-flour or Wheaten meal, dextrin or thelr equivalents a decoction or an extract of the ordinary domestic onion or of other similarly actingclasses of leek, such as garlic, scallion or the like. Then, as required, also the usual and known means 6. 9.. oils, glycerin, wax or their equivalents, maybe used, in order to make soft and flexible the thread to be dressed.

Immediately or a short time after the addition has taken place, alterations in the nature of the dressing substance can be clearly seen. The dressing substance becomes, transparent and even, adopting a comparatively great viscosity, thus rendering it possible to draw it out into threads. In use the dressing material is then shown to be easily ab- Specification of Letters Patent.

sorbed by all the fibrous materials concerned here, andtoenter also with great facility into the interior of'the thread to be dressed, thereby increasing the effect and the durabil-ity of the dressing substance. The thread treated with such a dressing substance is given an uncommonly high tensile strength, and the dusting out andfalling out again of the dressing substance from the warp or respectively the impending getting woolly and losing consistence of the Warpthreads isfmaterially reduced. Conclusive tests have proved that thereby the out-turn of. the looms has been considerably increased and that the woven product obtained comes out better and more free from defects. Besides it has been shown by the tests that the dressing substance prepared in this way has no adverse influence'on the thread whether it be the most delicate-one; nor does any bad effect become apparent in the dyeing or finishing process to follow. If required, such a dressing substance can be easily and completely removed again from the thread by washing afterthe weaving process. On the other hand such a dressing substance is also fit for permanent finishing, additions, while the remainder of the process is carried out as follows. Further it has been ascertained by the tests that in working after the new nesses of yarn in a uniform composition andconcentration.

. The aforesaid valuable qualities of the dressing substance made according to the new process, are still enhanced by the circumstance that the very cheapest dressing material, say potato-flour, can be used and that also the means to be added can be provided at any time and atlow costs.

When required the usual preserving means can be adopted, in order to prevent deterioration of the weavers glue or the addition thereto, composed of the decoction of onions, made according to the new process, and to protect it against contamination and decomposition. It may be observed however that the addition of the decoction of onions has, to a certain degree, a preserving influence on the dressing substance.

The dressing substance made according to the new method, is resistant to higher temperatures and can be boiled up under pressure, without any difficulty; this, 6. 9., is not so when the starch, used as a dressing substance, is dissolved by means of diastase.

According to whether it is intended to produce a dressing substance for warps or hanks of cotton, cardedor combed woolyarn or else a dressing substance for linen or jute or the like which after the weaving process is to remain in the thread as an admixture for finishing, the new method shows certain variations in the selection of the dressing stuffs. For the majority of cases, however, the cheap potato-flour is used according to the new process as a dressing substance, and I now give the process for the preparation of a weavers glue particuarly fit for dressing cheviots, carded and combed woll-yarn-warps.

Approximately half a kilo of ordinary domestic onion is boiled for nearly 30 minutes in two liters of water, the decoction being pressed off from the solid residues and about 18 grms. of linseed-oil being added. Such admixture is boiled up again in order to render the union of both ingredients as intimateas possible. Nearly half a liter of this mixture is added to a paste made of 100 liters of water and approximatey 8 kgs.

of potatofiour and prepared in the manner as used in the manufacture of dressing substances, whereupon the whole mass is boiled up once more. The dressing substance is then ready for use and can be used for dressing without any further additions.

In conclusion it is still to be observed, that common kitchen-onions can also .be replaced by other vegetables having a similar effect. Likewise such pastes of meal, starch decoctions of dextrin or glue, admixed with the juice of onions, can likewise be used to advantage in other industries, say wherever it is of importance to increase the binding power of these specifics, f. i. in the papermanufacture.

I claim A process for preparing a paste used as a weavers glue or for other similar dressing purposes consisting in boiling the ordinary domestic onion in water, separting the decoction thus obtained from the solid residues, adding linseed oil to the decoction and boiling them together, then mixing the substance with the paste as usually prepared in the manufacture of dressing substances and finally boiling them all together.

In testimony whereof I aflix my signature in the presence of two witnesses.

PAUL REIMANN.
